+# 1. Goal
+A mobile knife sharpening service visits restaurants and sharpens their knives.
+The office needs a summary of the sharpening fees of each customer for a period.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}SHARPEN is in package $TMP and contains data.
+  Fields: ITEM_ID (INT4, key), CUSTOMER (CHAR 10), KNIFE_TYPE (CHAR 5),
+  KNIFE_COUNT (INT4), SHARP_DATE (DATS).
+  One row is one item of a sharpening round.
+- Table {{P}}KNTYPE is in package $TMP and contains the price list.
+  Fields: TYPE_ID (CHAR 5, key), PRICE (DEC 15,2).
+  PRICE is the fee for one knife of that type.
+
+# 4. Contract
+- Create the executable program {{P}}SHARP_SUM in package $TMP.
+- Selection screen:
+  - Parameter P_FROM, type DATS, mandatory: the first sharpening date to include.
+  - Select-option S_CUST for the customer.
+- Show the result with CL_SALV_TABLE. The output table has these columns, with
+  these names:
+  - CUSTOMER: the customer.
+  - KNIVES: the total number of knives.
+  - FEE: the total fee. FEE is an amount with two decimal places.
+
+# 5. Business rules
+1. Include an item only if SHARP_DATE is on or after P_FROM and CUSTOMER is in
+   S_CUST.
+2. Include an item only if its KNIFE_TYPE has an entry in {{P}}KNTYPE.
+3. The fee of an item is KNIFE_COUNT multiplied by the PRICE of its knife type.
+4. Show one line for each customer that has at least one included item.
+5. KNIVES is the sum of KNIFE_COUNT of the included items of the customer.
+6. FEE is the sum of the fees of the included items of the customer.
+7. Sort the lines by FEE, the highest fee first.
+
+# 6. Constraints
+- Release target: 7.58.
+- Coding standards: Clean ABAP. Read the sharpening items and the prices with
+  one database access. Do not read the database inside a loop. Keep the methods
+  below 40 statements.
+- Out of scope: do not change {{P}}SHARPEN and {{P}}KNTYPE.
+
+# 7. Acceptance
+- The program is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests as local test classes in the program.
